previous standards.
To display a program at a specific resolution, you must

colors that a program can display depends on the
capabilities of the monitor, the video driver, and the
amount of video memory installed in the computer.

your computer's hardware and customize the computer's
operation by setting such features as password protection
and energy management. Some options in the System
Setup program require that you reboot the computer
(or the computer may reboot automatically) in order
to make a hardware configuration change. Because the

are connected in a series, you may need to enable or
disable the termination on these devices by changing
jumper or switch settings on the devices or by changing
settings in the configuration software for the devices.
